BICYCLE-FRAM E.

SPECIFICATION forming part of Letters Patent No. 617,604, dated January10, 1899.

Application filed January 12, 1898. Serial No. 666,449. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, JOHN A. REED, a citizen of the United States,residing at Morvin, in the county of Clarke and Stale of Alabama, haveinvented certain new and useful Improvementsin Bicycle-Frames; andldohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has reference to a novel construction in a bicycle, andit relates more especiali y to the structure of the bicycle-frame, theobject being to provide an adjustable frame which can also be takenapart quickly and conveniently, so that it can be packed in a smallcompass for transportation or otherance with this invention.

and enters the groove 4 in the stem 3.

A further object of the invention is to furnish improved means foradjusting the saddle.

The invention consists in thev features of construction hereinafterdescribed and specically claimed.

In the accompanying drawings,forming part of this specilication, Figure1 is a side elevation of a bicycle-frame constructed in accord- Fig. 2is a top plan view. Fig. 3 is a vertical longitudinal section taken onthe line 3 3 of Fig. 2. Fig. 4is a horizontal section taken on the linei 4t of Fig. 1.

Referring now to said drawings, 1 indicates the steering-head, and 2 thesteering-post. The stem 3 of the handle-bars is straight and extendsini-o the steering-post 2, while on its rear side it is provided with alongitudinal groove el, it being understood that the stem lits snuglywithin said post. The cap 5 holds the `upper set of balls in place, andit is held in place by a jam-nut 6. A set-screw 7 extends through saidcap 5 and through an opening S in the upper end of the steering-post Inthis way it is seen that the set-screw can be clamped tight to hold thehandle-bars in the correct position; but when it is desired to raise thehandle-bars the said set-screw can be loosened to allow the stem 3 tomove longitudinally, it being obvious that the stem will not turn, owingto the fact that the end of the set-screw 7 is situated within thelongitudinal groove 4 therein. The cap 5 is provided with a plurality ofscrew-threaded openings 9, so that the cap can be turned to compensatefor wear and yet permit the set-screw to be inserted.

The frame of the bicycle is similar to what is known as the diamondframethat is to say, it is provided with a top frame 10, the lower frame11, the backstays 12, the back fork 13, and the diagonal frame 14. Theseparts are connected together in an adjustable and also separable manner,so that the frame of the bicycle cannot only be adjusted, but the framecan be quickly taken apart and dismembered. There are two top frames orbars 10 and their front ends enter the sockets l5, that projectrearwardly from the steeringhead. The front ends of these bars 10 areheld within the sockets by means of set-screws 16while the rear ends ofthe bars 10 extend through openings in a seat-block 17 and are heldrigid with relation thereto by the setscrew 18. To the rear ends of thebars 10 are secured coupling-fingers 19,such construction preferablycomprising a bifurcated rear end of the bar 10, between which thereduced forward end of the coupling-finger is pivoted.

The backstays 12 are hollow and their upper ends receive the fingers 19,while said stays are provided with set-screws 20 for holding saidcoupling-fingers in place. Near the rear end of the back fork are theupright projections 21, to the upper ends of which the lower ends of thebackstays are pivoted. The crankhanger 22 is provided withrearwardly-extending fingers 23, that enter the forward ends of thesides of the fork 13, the forward ends of the sides of the fork beingsocketed and provided with set-screws 24: to engage said fingers 23. Onthe front side of the crank-hanger there is anger 25, that enters thelower socketed end of the lower frame 11 and is held therein by aset-screw 26. The upper end of the lower frame 11 enters the socket 27,projecting rearwardly from the steering-head, and which is also providedwith a set-screw 28 to engage the upper end of said lower frame.

The seat-block 17 is provided with the upright l rear side, throughwhich the set-screw 32 evtends, whereby said set-screw serves to holdIOO both the seat-stein no and said socket 3() rigid with relation tosaid seat-block 17. To the lower end of the socket 30 the diagonal frame14 is pivoted, the lower end of said 'frame being pivoted to the upperend of an upright projection 34 upon the crank-hanger.

It will he seen from the 'foregoing description that a bicycle-frameconstructed in this manner can he readily adjusted, as is obvious,and,further1nore, that it can be quickly taken apart by loosening theseveral set-screws referred to.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination with the steering-head of a bicycle-frame, thesteering-post provided with an opening andthe cap at the upper end ofsaid steering-head provided with a plurality of screw-threaded openingsto receive a setscrew, of the Stein of the handle-hars eXtending intosaid steerin g-post and provided with a longitudinal groove to receivesaid set-screw.

2. In a bicycle-frame, a steering-head with which the front ends of thetop and lower frames are adj nstahly and separably connected, thebackstays pivotally, ad j ustahly and scparably connected with the rearend of the top frame and pivoted at their lower ends to the rear endportions of the hack fork, of said back forks ad justably and separablyconnected at their forward ends with the crankhanger, said crank-hangerbeing adjustably and separably connected with the lower end of the lowerframe, and the diagonal frame pivotally connected at its upper end withthe top frame and at its lower end with the crankhanger. v

3. In a sectional bicycle-frame the several parts of which arerelatively adjustable, the seat-block adj nstably mounted upon the topframe and provided with an opening, asoeletpiece extending through saidopening, a setscrew, and the diagonal frame pivotally connected with thelower end of said socket-piece and pivotall7 connected at its lower endwith the crank-hanger.

In testimony whereof I affix my signature in presence of two witnesses.i
